First, the configuration of the first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, a coating liquid container 1 includes a container main body 10 that stores a coating liquid (not shown) such as a nail polish, and a lid body 20 that is fitted and sealed on a mouthpiece portion 12 of the container main body 10. And an inner plug 30 fitted into the container body 10. These are formed, for example, by injection molding a synthetic resin material, but are not limited thereto.

The container body 10 is integrally provided with a round-bottomed accommodation portion 14 in which a coating solution is filled inside a cylindrical outer wall portion 13, and a mouthpiece provided on the upper portion of the outer wall portion 13 and the accommodation portion 14. The part 12 is provided with an external thread 15.
The lid 20 is a cylindrical member having a top with a side wall 22 hanging down from an outer edge of a disk-shaped top wall 21, and a projection 23 is provided on an inner peripheral surface of the side wall 22. Further, a female screw 24 that can be screwed into the male screw 15 on the container body 10 is formed at the lower end thereof. Further, a packing 40 for securing the sealing property is adhered to the inner surface of the top wall 21 of the lid 20 via a double-sided tape (not shown). In addition, the structure which does not have the packing 40 may be sufficient. For example, the inner seal of the top wall 21 of the lid 20 is attached to the inner peripheral surface of the mouth tube portion 12 of the container body 10 so that the sealing property is improved. It may be a configuration that secures it.

As shown in FIGS. 2 and 3, the inner plug 30 is a member in which a flange 32 projecting annularly in the outer diameter direction is integrally provided at an upper end of a short cylindrical peripheral wall portion 31. Further, as shown in the present embodiment, a protruding plate 34 is integrally provided on the inner peripheral surface 33 of the peripheral wall portion 31 constituting the inner plug 30.
The protruding plate 34 has a pair of base ends 34 a provided on the inner peripheral surface 33 of the peripheral wall portion 31 and a front end 34 b protruding from the base end 34 a in the container axis O direction. The distal end portion 34b is formed so as to have an inclined posture that is lifted upward with respect to the portion 34a.

As shown in FIG. 4A, the protruding plate 34 has a distal end 34b formed in a circular shape in a plan view, and a base end 34a formed with a through hole 35 that opens in a substantially semicircular shape. The distal end portion 34b is formed with a radius of curvature R2 smaller than the radius of curvature R1 of the through hole 35 on the base end portion 34a side (R1> R2), and is convex upward and has a cross-sectional curved shape in the width direction. (See FIG. 4C), and the projecting plate 34 is formed in a shape resembling a claw shape as a whole.
Here, the width direction is a direction intersecting a virtual axis x (see FIGS. 3 and 4) passing through a midpoint between the pair of base ends 34a and the front end 34b (for example, line cc in FIG. 4). However, the width direction also includes a direction intersecting at a certain angle around the axis of the virtual axis x.

Further, as shown in FIG. 3B, an edge 36 which is formed at the upper end side of the through hole 35 of the protruding plate 34 and protrudes toward the inner peripheral surface 33 and is formed at an acute angle is provided. A roundness 37 is formed at the upper end of the distal end portion 34b along the distal end portion 34b.
In addition, the inclination posture of the protruding plate 34 is not limited to the inclination posture in which the distal end portion 34b is lifted upward with respect to the base end portion 34a as described above. For example, as shown in FIG. On the other hand, the tip end 34b side may be inclined downward.
Further, it is possible to have a configuration in which the through hole 35 is not provided between the inner peripheral surface 33 of the inner plug 30 and the protruding plate 34, but by adopting the configuration having the through hole 35 as described above, For example, the bristle portion 51 side of the brush 50 is inserted into the through hole 35, and the shaft portion 52 is connected to the base end portion 34a of the protruding plate 34 or the flange 32 of the inner plug 30. , The brush 50 can be held upright in the container body 10.

  In the coating solution container 1 having the above-described configuration, the inner plug 30 is fitted to the open end 11 of the container body 10 in which the contents are filled in the storage portion 14, and the packing 40 is provided on the inner plug 30. The closed lid 20 is screwed into the mouthpiece 12 of the container body 10 and sealed by being crowned.

Next, the operation of the coating liquid container 1 will be described.
The coating liquid container 1 is used with the lid 20 unscrewed and the inner plug 30 exposed to the outside. The user attaches the application liquid to the bristle portion of the brush by inserting a brush that constitutes one mode of the applicator into the accommodating portion 14 through the inner plug 30.

  For example, when the amount of the coating solution absorbed by the bristle portion of the brush is large, an ironing operation in which the shaft portion of the brush is lifted vertically upward while the root portion of the bristle is lightly brought into contact with the edge 36 of the protruding plate 34 is performed. Good to do. As a result, the excess coating liquid is squeezed out from the bristle of the brush by the edge 36, so that the amount of the coating liquid contained in the bristle of the brush after the squeezing operation can be reduced.

  Further, the user can perform the trial application of the coating liquid on the surface 34A by sliding the brush 34 in a state where the bristle portion is applied to the surface 34A of the protruding plate 34. Since the protruding plate 34 is formed so as to resemble the shape of a nail, the user can easily imagine the state of the surface of the nail after application by performing test coating without applying the nail to the actual surface of the nail. In addition, since the protruding plate 34 is formed so as to have an inclined position in which the distal end portion 34b is lifted upward, it is possible to perform trial coating as if it were applied to the actual nail surface, and at this time, The coating liquid that has been scraped off at 34A can be returned into the storage section 14.

Further, a rounded portion 37 is formed at the upper end of the distal end portion 34b of the protruding plate 34, and when the bristle portion of the brush is slid from the base end portion 34a toward the distal end portion 34b, the brush 37 is scraped off at the distal end portion 34b. Since the amount of the coating liquid to be applied is reduced, the amount of the coating liquid contained in the bristle portion of the brush can be reduced, and as a result, the test coating can be performed continuously. At the same time, it becomes possible to adjust the bristle portion of the brush on the surface 34A of the protruding plate 34 so as to be neatly arranged.
After use, the application liquid applied to the surface 34A of the protruding plate 34 can be wiped off with a tissue or the like, or removed using a remover, so that it can be applied again to the surface 34A.

Next, the configuration of a second embodiment of the present invention will be described with reference to FIGS.

For this purpose, the inner plug 30 can be mounted in the container body 10.

  Here, the engaging force between the annular engaging portion 31a of the inner plug 30 and the annular convex portion 12a of the container body 10 is the engaging force between the plurality of protrusions 32a of the inner plug 30 and the convex portion 23 on the lid 20 side. It is set larger than. Therefore, when the lid 20 is unscrewed and opened, the inner plug 30 can be left in the mouthpiece 12 of the container body 10. That is, in the coating solution container 1 shown in the second embodiment, once the lid 20 is once attached to the container main body 10, the inner plug 30 attached to the lid 20 in the initial state is replaced with the inner plug 30 after the attachment. It has a function as a moving stopper that can be moved to the container body 10 side. This makes it possible to smoothly perform the operation of filling the application liquid into the storage section 14 of the container body 10.

Next, a preferred embodiment of the lid constituting the coating liquid container 1 will be described with reference to FIGS.
